Sian Kaan Preserve

We made our way down the dirt road
past Tulum into the Sian Kaan Biosphere
Preserve, which has dozens of kilometers
of virgin beaches on the coast and a
virtually impenetrable interior, filled
with monkeys, big cats, and other fun
animals. Swimming on this beach, Jenny
gave us a hearty scare by getting caught
in an undertow. She escaped unscathed
but with a renewed awareness of her mortality.
